I think there's a lot of pressure on Pierce to score 25+ a night.
On the nose. Bogut is only scoring 14 a night and not in a particularly efficient manner (.49 FG% .42 FT%). I love Lowry, "Muddy" Fields and Ibaka. All are all high-effort, team-oriented players, and chippy, plus defenders but there isn't a reliable third option there.
The Bucks should get some offense off the bench from Reggie Williams - who isn't getting steady minutes in Golden State - and Gooden. Although Drew is out four-five weeks and is a mistake prone player that I don't think very highly of.
But this is a team that should be really strong on the glass and tough defensively with good size. Not an easy out.
And I do like the Hansborough pick for all the reasons you state. I'd target a better back up point guard next.
